In a past episode of the show, SHINee famously danced their “Replay” choreography to Lee Hyori‘s “U-Go-Girl.” Even though the songs sounded completely different, the choreography for “Replay” somehow managed to look as though it had been designed specifically for “U-Go-Girl.”

As it turns out, Red Velvet’s “Russian Roulette” goes just as perfectly with HyunA’s “Bubble Pop.” Astonishingly, the verses for “Bubble Pop” even start and end exactly when the members switch parts in “Russian Roulette.”

The choreography looked and felt so natural, some of the girls even started singing along!
